There are several good places to get a Free Political Blog in 2010
We use WordPress as a downloaded install on our own domain ronpaulblogs.com.
You can also use WordPress.com and get a domain like libertyfan.wordpress.com
Google’s Blogger is a good platform as well.
There are some microblogging sites as well like Tumblr or Twitter at 140 characters per post.
We recomend watching some videos here, read some tutorials, and then grab a blog where you want and start blogging.
